IMPROVEMNT IN SPRINGS FOR VEHICLES.

The Schedule referred to in these Letters Pxent and making part of thesame.

'I, ENOS l/VRIGHT, of the county of Lee and State of Iowa, have inventedcertain Improvements in the Mode of Applying Springs to "ehicles, ofwhich the following is aspecifieation;

-Nat'u-rc and Objects of the Invention.

The first part of my invention relates to the construction of a springbearer, in such' a manner that its upper side shall be attachable to theunder side or bottom of the body of the vehicle, and its 'under sideshall fornr a curve, which may be the are of a circle, or vary somewhatfrom it, as the case may be, and around which curve the'spring, which isattached to said bearer at or near the center of both spring and bearer,shall bend, touchingand resting'against said bearer, from the center'orpoint of attachment, toward both endsfjust in proportion as the weightof the load is increased, thus causing the spring to adjust itself totheweight of the load, and to be pliable with either a light or heavyload.

The second part of my invention relates to the construction andcombination with the spring-bcarer-sand springs, ofspring-holders orcouplings, roller'boX es and-rollers,'and rub-irons and plates, in sucha inanner that they may be applied to all kinds or" vehicles.

Description of the Accompanying Drawing.

Figurc'l is the body of a lumber-wagon, with spring-bearer and springattached.

Figure 2 is a bolster, containing roller-boxes and rollers, and towhichwearing-plates are attached.

Figure 3 is a roller-box.

Figure 4 is a roller,

General Description.

A is body of lumber-wagon, with spring bearer, spring, and springholders attached. I

B is the spring bearer, which is'made of wood, and is of a thicknesstocorrespond with the ,width of spring, and of a suflicient depth,tovgive. as much spring room between endsof spring and underside ofwagon-body, as isdesired. f

Said bearer is connected, with the wagon-body by bolts 1 1 1 1. I

O is the spring, and is a single bar, either of wood or steel, and isconnected with the bearer by bolts, 2 2.

1) I) are the spring-holders, and are made of iron,

the object of said holders being to hold the spring,

being secured to the under side of the same by bolts, .33 L5 3, to forma connection with the running part of wagon, by resting at pointsdirectly beneath D 'D,

on rollers, in the top of bolsters, shown by E Ein fig. 2; and also tohold the wagon-body from sliding back and forward, bythe perpendicularpart of the holders at 4 4 coming in contact with the side of the brfliters at points 5 5, in fig. 2, and to which points wearing-plates areattached, to prevent wearing by the. holders, into the sides of thebolsters.

, 6"6, in fig. 1, are wearing-plates, to prevent the bolster-stakes 7 7from wearing into the sides of the wagon-body.

8 is therub-iron, for the wheel to rub against when the wagon iscramped, as in turning, and is connected with the bearer by the pointsat the upper end being turned at right angles and driven into it.

. Fig. 3 is box, made of cast-iron, and is sunkin the top of the bolsterat E E, the object of the box being to form a firm cavity or trench forthe roller to work in.

Fig.4 is a roller, which is of iron, and is of the right length to dropeasily into the roller-box lengthwise with the b'olster, but it must nothave room enough to work much in that direction, and must be ofsuflicient diameter to fill about two-thirds the width of thcibox, andto rise about one-fourth of its diameter above the top or upper surfaceof the bolster, the

7 box being of proportions suitable for the purpose.

The object ofthe roller is to prevent wearing and friction by theholders on the top of the bolster.

The object of thesmall section, is

First, to show a difi'erent style oi finish of the bearer for lightwagons and carriages.

Second, to sl1ow, by the spring attached thereto, on the end marked A, adifferent kind of holder from that hereinbet'ore described. Thiskind,though objectionable on account of raising the wagonbody higher, may bepreferred by some on account of being cheaper, therefore I desire tohave it included.

Third, on the end of said spring, marked B, is the ykind ofcouplings'uscd for light wagons and carriages.
